This is the Chinese Butternut and it is abundant throughout Hupeh and Sze- 

 ch'uan. Usually it is a bush, but in moist woods it forms a tree from 12-15 m. tall, 

 with a trunk from 1-1.5 m. in girth. The bark is smooth and pale gray, becoming 

 fissured with age. The leaves vary in length from 45-90 cm.; the male catkins 

 are from 20-30 cm. long and the fruit is very glandular. 



We have not seen Juglans formosana Hayata (in Jour. Coll. Sci. Tokyo, XXX. 

 art. 1, 283 [1911]), but from the description we suspect that it belongs here. 



Pictures of this tree will be found under Nos. 344, 370 of the collection of Wil- 

 son's photographs and in his Vegetation of Western China, Nos. 258, 259. 



Here may be added notes on two genera not collected during the Arnold Ar- 

 boretum expeditions.
